We were assigning I2C bus controller instead of client as parent device. Besides being logically wrong, it messed up with devm handling of input device. As a result we were leaving input device and event node behind after rmmod-ing the driver, which lead to a kernel oops if one were to access the event node later. Let's remove the assignment and rely on devm_input_allocate_device() to set it up properly for us.
